Wireless Serial 6 Pin RF Transceiver Bluetooth Module HC-06 3.6V-6V Slave for Arduino

LED indicate the status of bluetooth connection: if the LED is flashing, it means the bluetooth does not connect, if the LED is light, it means the bluetooth connected
Anti-reverse diode, with 3.3V LDO
Input voltage: 3.6-6V,
Current: The current is 30mA when it is unparied, it is 10mA when it is paried. The input voltage can not over 7V
Interface level 3.3V, it can be connected with various SCM directly, such as: 51, AVR, PIC, ARM, MSP430, etc. It is not allowed to connected with MAX232
Effective Distance: 10 meters in the open field
After paried, it can be used as full-duplex serial, it do not need anything about bluetooth protocol, but only support 8 data bits, 1 stop bit and no parity communication format
When it without bluetooth connection, it support baud rate, name, passkey through AT command. The information will be saved when power is off. After connection, it will be changed to pass-through mode automatically
